This administration's legal theory is that executive power is concentrated entirely in the person of the president, which, to be fair, is because the Constitution says that it is.

That's not conducive to good government and is not the current precedent set by the Supreme Court, but it's been the conservative legal view since the 1980s and to be fair again, is again what the Constitution actually says. It will pretty much certainly be the prevailing view after this returns to the Supreme Court.

If that legal theory is true then Congress cannot create independent executive power and so it is not illegal for the President to fire anyone in the executive branch for any reason, including inspectors general, the chairman of the Fed, etc., regardless of any law to the contrary. Again, to be clear a third time, the effects of this will be bad, but the constitutional language isn't really ambiguous.
